Keyboard Shortcut for Recent Apps? topic

I'm trying to find a keyboard shortcut for my Nexus 7 2013 that will trigger the Recent Apps screen to come up. I know that ALT-TAB will let me scroll through the recent apps list, but that's not what I'm looking for. What I need is a keyboard shortcut that behaves exactly like the Recent Apps button on the nav bar, just bring up the Recent Apps screen and sit there and wait for more input. And this needs to be a keyboard shortcut that doesn't require me to hold a key down. I've been searching for hours and can't find a way to make this happen.
